Application filed November 3G, 1914. Serial No. 874,989.

To all ila/2,0m it may con' fwn:

lle it known that l, n'rnim C. SOCLE, a citizen oi' `the United States, residing` in the city and county ot flan Francisco. State oi California, (Whose postollice addres No. 22C Judah street.) have invented new and useful improvements in lll'indon' e .Clash MountingfsT of which the following is a speciiication.

rlhis invention relates more particnlarlj,r to moans l-orsnpnortino sashos slidahly piv-v oted in 'Window frames.

Among the objects of this invention are to produce a mounting' sirnplc in constrnction'` easily installed and adjusted; that Will give to the sash` as nearly as may he, uni form support in its various zuljnstnients, and evolutions; that is architectnrally and coinlnercially attractive; that will allow the sash to he completely reve 'sed and closed within tho opening; that ma)7 he laid ont.` partially assembled and the' inter-relation oi parts cstahlifshed in the factory, to facilitato its proper installation by the average Workman familiar with this class 'oll labor.

Other objects and advantages will appear as the description progresses.

In the drawingaccompanying and forining part of the present specification. to which like reference characters have heen applied, a. siinpleffriiiof putting this invention into practice is shown. l do not wish to he, understood as confining' this invcntion tothe disclosures made in Said drawing and-description, as mangi,Y variations may be introduced, within the spirit of this inventioo, as defined in the claims succeeding the said description.

This invention involves the pivoting of the sash, on opposite sides, on pivots frio tionally engaging' grooves in the opposite sides oi' the Window frame, to permit the swinging ot the sash in the'window trarne for ventilation. The movement of the sash is cont-rolled by a system of levers interposed. hetwcen thc sash and trarne, to hold the sash in any fixed 'position desired, aganst wind pressure or other sliitting i'orces. lhis type o'l sash is hard to control in its rarions evo lotions by the ordinary incans, owing to the shittingl halanco oit Weight iif'llcn the sash is shifted i'roin the closed or vertical plane.) to the Ilnll open or horizontal plano., and reversed and restored to the vertical `plane, or returned to the rloscd position Without rerorsal. Heavy sashcs are particularly hard to control when opening or closing', in their departure from the verticahposition. There is a period in the operation of a lever support in passing a center, at which the soir porting! power is comparatively nil, until the ratio ol? snipporting power is again restored to the lever and removed -from the sash, that is one of the lerer elements in the coinhination ot support lovers.

In the present invention, the relative proportions and conihinativc actions of the Various levers, are alivllls in favor ol the snpporting4 nioiinting, as against the Weight of the sash that is'thc load to he supported; rl permit the control pivot he placed at dit snll'ciently near to the center of the sash to allen it to he completely reversed Within its opening', and so close the opening in the reversed position, that vweather is excluded, a i J substantial advantage in Window washing during severe weather.

ln the drawings Figure l is a perspective view of a conventional Window l'rarne, having upper and lower sashes mounted therein, in accordance with this invention, the 'opper sash being shown in the onen position' and the low r sash in the closed position. Fig., 2 a fragmentary enlarged detail of the sash and its supporting and control nionntine, with the Window framing' omitted. Fig. 3 is a fragmentary detail, practically full size, in cross section on the lino Ulf-lll, Fig. 2, illustrating' the inter-relation oit the saslnthe guido Weather strip, the control levers and the side stile oit' a Window traine, Fig. i is a similar view. illustratingthe springv actuated sliding pivot mounted in the corner of the sash and hearing within the `groove of the guide strip, all shown. in cross Sec i n7 except thc pi ot and its actuating sprl-n: Fig. is an 'isoinctrical perspective from hehind, illnstratin the pivot plato for the carrier arm engaging the hinge plate oft the guide Strip,

ln detail the construction illustrated in the drawings, includes the window :training composed oi" 'the sill. l, the stool the side stilea oonnected across 'the top hy the lintel ll. the usual stops 5 and other weatl'ierjprool ing elements and finish. who side Stiles l are prov' led with the. lgrooves G- on opposite sid-cs olr the tramo. to receive the guide Weather strips T. These froide strips illnetratcd in cross section in Fig'. 4f fit lfmstl;7 Awithin the grooves G, and extend from the sill l to tho lintcl l, being out to this proper 'lll length in the factory, according to the meas-v urement of the frame between the sill and the lintel. These guide strips are held withing the grooves 6 by the hinge plates 3, provided with countersunk holes 9, to receive screws driven into the body of the strip 7, the plates 8 being gained into the strips flush with the surface. The angular extensions 10 of the plates rest against the surface 11 of the stiles 3, and are provided with countersuiik holes 12 to receive screws driven into the Stiles 3. These latter screws are not driven tight, and allow a Lfreehinge move ment of the strips 7 within grooves 6, permitted by the play of the screw in the opening 12, the purpose of which will be hereafter fully described.

The upper' and lower sashes illustrated are alike in construction, arrangement and operation, except as to their location in the upper and lower portions of the window trame respectively. They include the side sash stiles 13 and 14 and the upper and lower rails l15 and 16 and 17 'and 18 respectively.- Owing to this similarity of the 'sashes, the following description of `one sash will be understood to apply toboth, as a window is often provided with one sash only, but may have any number of sashes in the same traine.

rElie opposite upper corners of the sash are provided with resilient pivotsI (see Fig. 4) including the heads 19 engagingthe grooves 20 in the strips 7, and the stems 21 having a shoulder 22 with the abutting' washer 23 against which the end of the spring 24 bears. The whole is inclosed within a sleeve 25 crimped into the plate 26, gained into the side stiles 13'of the sash. The Ainner ends ot the sleeves are turned in' as at 27,v to guide the end ot' the stem 21.l and to provide an abutment `for the opposite end of the spring 24 extending' between the end of the sleeve and the' washer 23. The combined tension of tl'iespring's E24 forces the heads 19 against the bottoms of the grooves 20, with sufiicient force to exert a. friction equal to supporting the weight of the sash pivotally suspended on the stems 21. This amount of spring tension preferable but is not arbitrary. It may be more than suiiicient to support the sash, as described, or it may be less, without materially affecting the operation of the control mounting; any excess tension would be overcome by the operator in manipulating the sash, and any deficiency ot tension would be compensated `tor by the novel arrangement of the Vcontrol levers.`

The backs'o the strips 7 are milled at an angle at 28, and the holes 29 bored therein at thev pro-per intervals, to receive the coil springs 30, expanding between the bottoms of the holes and the bottoms of the grooves 6. The combined tension of these springs is considerably more than the combined tension,

and fixed thereto by the screws 33, on oppo; To these plates the site sides of the sash. control arms 34 are pivoted at 35, the opposite ends of these arms being pivoted at 36 to the control links 37 pivoted at 38 to the plate 39, fixed to the side Stiles 3 'by the screws 40, adjacent to the guide strips 7. Intermediate the pivots and 36, the support arm 41 is pivoted at 42 to the control arm 34, preferably slightly above the middle between the pivots 35 and 36. The opposite end of the support arm 41 is pivoted at 43 to the plate 44, having an offset portion 45 overlying,r the angle 10 of the hinge plate 8 and provided with a slot 46 engaging a hook 47, formed on the end of the plate 8, bent at an angle to the extension 10; these hooks act as indices to locate the plates 44. The plates 8 are fixed to the guide strips 7, inthe proper exact position between their opposite ends, to properly locate the suspending pivots 43 ot the support arms. This point is indicated by placing the sash or sashes in their proper relative position with the control levers in their proper position, the location of the plates 8 then noted on the strips 7, to which they lare securely fixed and left thereon. The offset plates 44 are then unhooked from the plates 8, so that when the guide strips 7 are properly placed in the grooves 6 in they window frame, (wherever it may be located) it will bring` proper position to receive the plates 44, when the sashes are assembled within the frame, when the plates 44 may be securely xed to the side stiles 3, by screws driven therein through the holes 43; insuring the proper interrelation and combination of the various elements contributing to the operation of the'- sash or sashes within the frame, without de:

pending,r too much upon the discretion of workmen outside of the factory, where the embodiments of this invention are produced.

This invention operates substantially as follows, prcsumingi the sash to be ymounted v'in the frame as described, and resting in the closed position illustrated in the lower sash in Fig. 1, the control arm 34, the support arm 4l and Athe control link 37 lying' parallel in vertical alinement adjacent to' the outside o'i' the sides of the sash; the

4pivots 33 and 43 being placed in vertical alincmcnt and the upper end ot' the lever offset, as at 49, to accomplish this par the hooks 47 in the @all allel nesting of parts; the length of the link 37 being proportionate to the location of the pivot 2, so that the link lies beneath the support arm ll in the close position. rlhe control lever mounting is duI licated on opposite sides of each sash, to insure the proper' balance of the sash in its various evolutions.

To open the window, as illustrated in the upper sash in iig. Il, the. operator pushes outward on the lower rail 18 of the upper sash, pushing it into the position shown. This carries the pivotal centers outward, opening the control mechanism into the relative position illustrated in Fig. 2. The outward movement oi the control arm 34C swings the support arm 4 1 outward on its pivot 43; the outward swing oi' the lever ll elevates the pivot 42, which causes the center of the sash t0 move upward lifting the lower rail 1S and causing the descent of the -upper rail 1G, on the opposite side of the fulcrum re )resented by the )ivots The friction exerted by the pivot heads i9 in the grooves 20, holds the sash in any position chosen by the operator, the overhanging weight of the sash being supported by the pivot 43, through the control arm 3i and the support arm ll. ln the positions illustrated in IFig. l the weight ot' the sash is below the pivotal centers 2l; this tends to swing the pivots 35 inward and the pivots 36 outward, putting a tension on the link 37 and theI support rod 4l, oii'set by a compression force exerted between the pivots 35 and the pivots 21, the pivot 4t2 being the tulcrum of the ,lever This condition holds until the sash. reaches the horizontal position, and those positions in which the overhanging weight of the sash above the pivots 2l, as in reversing the sash within the opening of the trame, to present the normally outside surface of the glass to the inside of the room, for the purpose of washing, etc. With the over-hanging weight of the sash above the pivot 2l (in the reverse position), the weight oi the sash pulls cutward on the pivots 35, Lputting a compres sion strain on the links 37 offset by the tension always remaining onl the support arm 4l, in all positions of the sash. Since the weight of the sash is transmitted through the' control arm 3l to the support arm el, and is controlled in its movements largely by the control arm ill, it is obvious that the more nearly the control arm approaches the vertical, with respect to the horizontal movement ot the sash, the better will be the sup port and control exerted by this arm l-l. rlhe logical way to meet this condition Vwould be to extend the length of the arm Bil downward, to the point of conjunction with the vertical line of the window traine, at which point it would have to he slidably pivoted, the mechanical objections to such a construction are suiiiciently evident. These objections are very simply obviated by controlling the nether end of the control arm by connecting it to the frame by the link 31. The tension and compression strains intercepted by the link 37 are relatively equal in the various evolutions ot' the sash, the support and control of which is practically uniform in all of its various positions, owing to the peculiar distribution of the strains across the various levers, all of the parts being positive in their actions, excepting the resilient, spring imparted friction, between the grooves :'20 and the heads A19 of the sash pivot.

The upper sash is provided with the V shape groove in the under side of-the lower rail, to lit the tapered upper edge 'of the rail l5 of the lower sash. ln closing the sashes the upper sash is closed iirst, then the lower one is pulled shut, which forces the upper edge ofthe rail l5 into the groove 50 in the lower edge of the upper sash, making the joint between the sashes waterproof. When the lower sash is locked by a suitable latch, `neither of the sashes can be opened from either side until this latch is unlocked.

Having thus described this invention, what l claim and desire to secure by Letters Patent is:
